The Criminal Investigation Division (CID) is the investigative resource of the Oregon State Police and delivers statewide services in support of the Agency's Vision of providing "Premier Public Safety Services for Oregon."

​

The CID Major Crimes Section, the Drug Enforcement Section, and the Sex Offender Registration Unit work in conjunction with other state police divisions to enhance livability and safety by protecting the people, property, and natural resources of Oregon.

​

Detectives are strategically located across the state to support local law enforcement with major criminal investigations and on interagency teams. They also provide primary criminal investigative services on state property and at state institutions.
